A Highly Reflective Atmosphere on the Lava World TOI-561b Revealed by JWST/NIRSpec Phase Curve
Samuel Boucher, Lisa Dang, Alex McGinty +15
Ultra-short period (USP) rocky planets are expected to be depleted of any substantial gaseous envelope due to the intense irradiation they receive from their host star, making the…
An Evolving Cosmic Shoreline and Sandbar Bounding the Rocky Airless Valley
Barron K. Nguyen, Laura K. Schaefer, Xuan Ji +7
Recent JWST observations challenge the traditional 'cosmic shoreline' from both sides, revealing thick volatile atmospheres on the hottest close-in 'lava worlds,' where irradiation…
Coupled atmospHere Interior modeL Intercomparison (CHILI). I. Evolutionary Modelling -- Primordial Magma Oceans of Earth and Venus
Harrison Nicholls, Joshua Krissansen-Totton, Tim Lichtenberg +22
Earth and Venus represent two evolutionary outcomes arising from initially molten 'magma ocean' periods, followed by lifetimes of chemical and geophysical divergence. Their physics…
A Thick Volatile Atmosphere on the Ultrahot Super-Earth TOI-561 b
Johanna K. Teske, Nicole L. Wallack, Anjali A. A. Piette +10
Ultrashort-period (USP) exoplanets -- with R and periods 1 day -- are expected to be stripped of volatile atmospheres by intense host star irradiation…
